Peripheral Persistent Fetal Vasculature: A Report of Three Cases.

The authors report three cases of persistent fetal vasculature (PFV) presenting with an atypical peripheral fibrovascular stalk. A 5-month-old with congenital exotropia with a vitreous hemorrhage in the right eye underwent vitrectomy, and a mid-peripheral vitreal vascular stalk was visualized within the area of hemorrhage. The second case is of an 8-year-old with two fetal vascular remnants in the right eye: (1) a stalk superotemporally extending from the pars plana to the mid-peripheral retina that was associated with a retinal break and (2) a focal lens opacity. The third case is a 12-year-old with a history of familial exudative vitreoretinopathy and peripapillary choroidal neovascular membrane found to have a peripheral vitreal stalk in the right eye. These cases demonstrate a rare form of PFV with primarily peripheral remnants. [Ophthalmic Surg Lasers Imaging Retina. 2018;49:e83-e88.].
